Study Notes

Disadvantages of Oral Method

One disadvantage of the oral method of drug administration is that it may not be suitable for certain patients.

Advantages of Subcutaneous Injection

Subcutaneous injection is advantageous for drug administration because it allows for a slower and more consistent release of the medication.

Disadvantages of Subcutaneous Injection

The chief disadvantage of subcutaneous injection is that it may cause tissue irritation or inflammation.

Limitations of Oral Method

Limited use of the oral method is observed in some patients because it may not be effective due to factors such as gastrointestinal disturbances or liver disease.

Subcutaneous Tissue Location

Subcutaneous tissue is located beneath the skin.

Importance of Aseptic Technique

Aseptic technique is important for needle injections to prevent infection and ensure the safety of the patient.

Allowing Antiseptic Solution to Dry

Allowing the antiseptic solution to dry on the skin surface prior to the insertion of the needle helps to prevent bacterial growth and reduce the risk of infection.

Intradermal Injections

The upper arm area is commonly used for intradermal injections.

Advantages of Intramuscular Injections

Administering drugs through intramuscular injection is advantageous because it allows for a faster and more consistent absorption of the medication.

Patient Positioning for Gluteal Injections

The patient should lie on their side with their knees bent for an intramuscular injection to the gluteal muscle.

Palpating the Muscle

Palpating the muscle before inserting the needle for an intramuscular injection helps to identify the correct location and avoid nerve damage.

Irritating Drugs

Drugs that are irritating to subcutaneous tissue are often given through intramuscular injection to avoid tissue irritation or inflammation.

Intradermal Injection Angle

A 1.2 cm (1/2 inch) needle should be inserted at a 10-15° angle for an intradermal injection.

Expelling Air from the Needle

Expelling air from the needle before injection helps to prevent the injection of air into the tissue, which can cause discomfort and other complications.
